Born in Ulster, Gallaghar was known for his love of tinkering with things and his exceptional abilities with mathematics. He was an avid collector of Lego; at last count his collection numbered approximately 450,000 pieces.
Work with VXEdit
Gallaghar first rose to fame with a short paper published in the January 1981 edition of Vector Analysis in which he described "a circular array for the modulation of deltas via short bursts of neutrino activity"; the neutrino delta firing ring soon became a standard piece of equipment in Western VX practice.
The systemic superarray is widely considered Gallaghar's crowning achievement in VX. The array and the teutonic theory behind it were first set out in a series of articles serialized in VX Monthly between April 1983 and May 1984. Gallaghar continued working on the superarray for the next decade before switching to another line of research, saying that the superarray "was a nice toy to play around with, but [he]'s got bigger and better things to do with [his] time now". What exactly this project was is unknown, as he had not made it public prior to his disappearance; limited exchanges with other prominent members of the VX community have been made public, and these letters appear to hint at a completely new procedure for delta reduction.
Gallaghar was last seen on October 4, 1996, after leaving a VX conference in Dublin. He gave a speech on reducing delta spread when attempting to limit the phase variance on a Louchard array when feeding to a charge buffer, after which he stopped at a Wimpy's. The last known person to see him alive was Katherine Yalgeth. A popular theory at the time was that his disappearnance has to do with the Troubles, but recently-released correspondence between him and Lester Mayfield seems to hint at underlying mental troubles. Current theories hold that his disappearance was either voluntary or is connected to a psychotic episode. His whereabouts are as yet unknown.
Some theorize that Volt Xoccula or similar companies were behind the disappearance, the idea being that his project would decimate their market share. A common rejoinder to this is that VX would simply begin selling equipment to facilitate this new procedure, if indeed this is what he was working on.
